CocoRosie is an American duo formed in 2003 by sisters Bianca "Coco" and Sierra "Rosie" Casady. The sisters were born and raised in the United States (Sierra, the older of the two, was born in Iowa, and Bianca was born in Hawaii), but formed the band in Paris, France after meeting for the first time in years. Their mother nicknamed them Rosie and Coco, respectively, from which their musical act takes its name. Their music has been called freak folk, and incorporates elements of pop, blues, opera, electronica, and hip hop.
